 * Create the Long Tail Human Queue MCP server.

 * Registers five tools that expose the escalation API:
 * - escalate_to_human — create a new escalation (fire-and-forget)
 * - check_resolution — check escalation status
 * - get_available_work — list available escalations by role
 * - claim_and_resolve — claim + resolve in one step
 * - escalate_and_wait — create escalation and return signal for durable wait
 *
 * The server is created with tools registered but no transport
 * auto-connected. Callers connect a transport programmatically
 * or via the Streamable HTTP endpoint.
